Based on my observations, there appears to be sufficient support among council members to implement registration and some restrictions.

I live really close to it and I was thinking it would be a good choice for me to start there as it´s cheaper than Barcelona and it also has an ok University.

I won't have to do this again for 20+ years.Electrical in most of these homes is usually sufficient unless you still have knob and tube. 

But we made one decision that history may one day show was the wrong choice--our rate is floating. 

We had to request correction of multiple other items that we did not feel were finished with sufficient attention to detail.

.- These total 10 duplexes should bring in 30K gross rent per month and cash-flow about ~3-4K/month.We don't plan to use any of the cash-flow for personal expenses and after keeping sufficient reserves, we will funnel the cash-flow to pay-off existing properties.

The earlier you recognize this, the better off you will be in the long run "I was wondering if any lenders out here on BP are willing to play game...." is not the best choice of words.  

Hard money lenders, familiar from your experience with flips, remain a viable choice, although they typically come with higher interest rates and shorter repayment terms.

Insurance is great and absolutely required but it may not be sufficient if a renter or tenant comes after you.I have always suggested that investors go in highly leveraged.  

Having an experienced agent on your team before the rehab i think is very important because it is during the rehab when they can help add the most value by pointing you in the direction of what adds value to the sale, what finishes to choose and what to avoid, even what color paints are a good choice, insuring that your target sales price is not just realistic, but that it can actually appraise for that amount.
